This Würth Elektronik webinar aim to show where the difference between calculation and measurement of PCB heat dissipation comes from, even for relatively simple assemblies. Without time-consuming thermal simulations, demanding heat dissipation of assemblies cannot solve satisfactorily. But, to what extent can simple thermal requirements on PCBs be determined with basic mathematics? How well do Read the original post at Correlation between Calculation &...

Full paper download The paper presents effects of derating on performance and reliability of Solid Electrolytic and Polymer Tantalum capacitors manufactured with conventional technology and flawless dielectric technology (F-Tech) combined with simulated breakdown screening (SBDS). Solid tantalum capacitors that can be used in high-reliability applications with low/no derating and are efficient, reliable, and cost effective are under discussion.  The paper was prepared by Yuri...

This video from Würth Elektronik elaborates on clearance and creepage distance and solid insulation materials. Many applications of fire are productive and warming. Fire can be a real risk if the components on pcb has not been selected correctly for high voltages. In some circumstances, incorrectly selected components can create Transient voltage, which could cause Read the original post at Creepage and Clearance of...
